HyperFlex Control Arm Bushings

A control arm bushing plays a vital role in a suspension. Replace that faulty O.E. rubber bushing with an Energy Suspension Hyperflex control arm bushing. These polyurethane bushings provide the longevity and performance needed to maximize a suspension's efficiency. Energy Suspension's Hyperflex polyurethane is a firmer bushing than the O.E. Not only does this increase the longevity of the bushing but gives the suspension a boost in handling performance. With a firmer bushing, there will be a slight increase in NVH (noise, vibration, and harshness), but most drivers prefer the boost in performance in spite of that.

The Faulty O.E.

As your suspension travels, a rubber control arm bushing is repeatedly stretching and flexing. After a while, the center sleeve begins to sag and your suspension alignment is throw out of whack. The sagging will go on until the rubber fails completely.

Be sure to use Formula 5

A control arm bushing rotates a lot against the metal shell, so make sure you grease it well with Energy Suspension's own Formula 5 Bushing Lubricant. Using plenty of grease is the best way to ensure a long lasting part without any squeaking. If you'd like some extra grease just in case, pick up an extra 3 pack or an 8 ounce tube.

Color

Energy Suspension makes parts in 2 colors. Red and Black.

How are these two colors different?

The only difference between the red and black parts is that most Black Energy Suspension parts are Graphite Impregnated. This serves to help self lubricate the bushings. The Red parts do not have this characteristic. Aside from the actual color and the lack of being Graphite Impregnated - the red parts are essentially the same as the black.

I thought that the RED parts were harder and more performance oriented?

This is a common misconception. The red parts have the same durometer (hardness) as the Black parts and differ only in their actual appearance (color) and the fact that they're NOT graphite impregnated like the Black parts.

Why do people buy the red parts when they're not Graphite Impregnated like the Black parts?

In the end this is really because some people simplylike the color Red more than Black.

I thought Energy Suspension Made parts in Yellow and Blue as well?

Unfortunately Energy Suspension stopped producing these colors a long time ago and they are no longer available on the market.
